If you put the term and its definition in paragraphs one after the other, it is a good idea to define a style for the term (called, say, GlossaryTerm) and another for the definition (called, say, GlossaryDefinition). You can use a table with or without borders, or you can put the term and its definition in separate paragraphs. Go to the end of your document, and type your glossary. Word has no built-in method of creating a glossary automatically, but you can use hyperlinks or the Table of Authorities functionality to create a glossary for one or more documents. The simplest way to create a glossary is to type your glossary by hand at the end of your document. To create a glossary across several documents, use RD fields and the Table of Authorities functionality. You can type one by hand, use hyperlinks, or use the Table of Authorities functionality. Word has no built-in mechanism to create glossaries.
